  • Alocação de recursos e tomada de decisão : o caso da Sonae MC
    Publication . Ribeiro, Diana Filipa Barbosa; Marques, Luís Manuel Dionísio
    O controlo de gestão tem vindo a assumir uma posição cada vez mais forte no mundo empresarial, no entanto a temática da alocação de recursos e da tomada de decisão que lhe estão associadas, são pouco abordadas na literatura. Assim, este trabalho tem como principal finalidade entender como a Sonae MC, empresa líder no retalho alimentar em Portugal, aloca os seus recursos e toma as suas decisões, nos seus diversos negócios, em função da garantia de que a empresa cumpra os objetivos traçados. A questão de investigação proposta a que este trabalho propõe responder é: “Quais as características e principais ferramentas utilizadas no processo de alocação de recursos e tomada de decisão na Sonae MC?”. Para tal, primeiramente, procedeu-se à descrição dos conceitos relacionados com o tema, do ponto de vista teórico. Posteriormente, com base na recolha de dados através das entrevistas realizadas a dois gestores corporativos e a dois gestores de negócio, foi possível recolher conclusões relativas ao tema em estudo, as quais são analisadas no capítulo 5. Através da análise do estudo de caso, foi possível perceber que a alocação de recursos e a tomada de decisão acontece durante o ciclo de planeamento e estratégia da Sonae MC, no momento da elaboração dos Planos de Ação e Recursos e do Orçamento. Assim, conclui-se que estas são as principais ferramentas utilizadas em ambos processos.

  • Packaging sustainability in organic food purchase behavior : a comparative analysis between Portugal and Colombia
    Publication . Martinez, Susana Gomez; Julião, Jorge Manuel Soares; Gaspar, Marcelo
    Given the current gap and lack of literature understanding the relationship between a consumer purchase behavior focusing on environment (sustainable packaging) and a consumer purchase behavior focusing on health (organic food), both having important impacts on current socio-economic trends and the ecosystem, this dissertation´s objective is to determine the relevance of packaging sustainability for organic food consumers in retail. Taking into consideration that the investigation was seeking to explain a relationship between two variables, a quantitative method through a survey strategy was chosen, selecting a questionnaire as the collection method. Then, the investigation premises were tested through Structural Equation Modeling, performing a factor Confirmatory Factor Analysis, followed by the assessment of the final structural model. After a thoughtful analysis performed on the collected data, it was possible to demonstrate that packaging sustainability satisfaction substantially impacts Attitude and Perceived Behavioral Control, variables of the consumer purchasing organic food, following the Reasoned Action Approach (RAA) model. Finally, a comparative analysis was performed between Portugal and Colombia with no major differences encountered among the two countries’ perceptions on packaging sustainability for organic food.

  • Use of olive leaf extract (OLE) to inhibit the growth of Campylobacter spp. in an active packaging for fresh chicken preservation : development of the packaging and overview of the literature
    Publication . El Ouazzani, Ismael Chahed; Poças, Maria de Fátima dos Reis Filipe Tavares; Teixeira, Paula Cristina Maia
    This work is composed of a bibliographic survey and an experimental part. The bibliographic part consists of a study on the epidemiological situation of Campylobacter spp. in Europe, advances in research on natural solutions for the conservation of chicken, studies aimed at reducing contamination by Campylobacter spp., the use of olive leaf extract (OLE) for the conservation of food, and other new alternatives for food preservation. The experimental part consists of a laboratory study on the effectiveness of OLE against Campylobacter spp. and its application in an active packaging for the conservation of chicken. The epidemiological situation related to Campylobacter infections in the EU is not homogeneous between countries and its related to the consumption of foods contaminated with these bacteria. Some seasonality has also been observed for infections. In recent years many studies have been carried out to develop new natural solutions for the conservation of chicken, due to the need to increase the shelf life of food. In these studies, new natural plants have been found as well as very effective minerals to lengthen the shelf life of food. OLE is a by-product of the olive industry that is widely used in phytotherapy, but in recent years it has been shown that it has a potential to increase the shelf life of food mainly due to its antioxidant and antibacterial effects. In microbiological studies it has been demonstrated its effectiveness against Campylobacter spp., however, there are no studies in the literature that have the objective of reducing or eliminating Campylobacter spp. in chicken with the use of OLE. For this reason, OLE was chosen to carry out an experimental study. In the experimental work, results from in vitro and in situ tests were in agreement. OLE has been effective as a growth inhibitor at the optimal growth conditions of Campylobacter spp., that is, at 41.5 oC and in microaerophilia. Nevertheless, once samples were removed from contact with OLE growth was observed, this means that the extract has not killed all the bacteria. The experimental design was not able to prove the efficacy of OLE in reducing the viable cell count at low temperatures.

  • Sustentabilidade ambiental como forma de promover a confiança dos consumidores da indústria hoteleira
    Publication . Pinto, Sofia Cardoso; Julião, Jorge Manuel Soares; Gaspar, Marcelo
    Em direção a um comportamento mais responsável em relação ao meio ambiente e a um padrão de consumo mais consciente, a sustentabilidade ambiental é um conceito essencial a ser implementado pela indústria hoteleira. Como tal, a integração da sustentabilidade ambiental na estratégia de negócio dos hotéis é uma abordagem cada vez mais comum. No entanto, existem desafios para as empresas deste setor revindicarem o seu compromisso ambiental melhorando a transparência e a credibilidade de tais compromissos, de forma a obter um maior grau de confiança nos consumidores. Neste sentido, esta dissertação foca-se em avaliar os atributos ecológicos que um hotel deve compreender para criar confiança nos seus clientes. De modo a responder a este objetivo, foram identificados e caracterizados conceitos considerados importantes dentro da sustentabilidade ambiental na hotelaria e realizado um questionário aos consumidores portugueses. Os resultados mostram a importância que os quinze atributos de sustentabilidade ambiental selecionados têm para os consumidores desenvolverem a confiança nos serviços dos hotéis e a relevância que estes devem ter na divulgação nesta indústria.

  • The impact of textual features on cost of equity capital : the case of UK annual reports
    Publication . Carneiro, Renato Filipe Peixoto; Alves, Paulo Alexandre Pimenta
    This thesis aims to analyze the impact of textual features of UK Annual Reports sections on the cost of equity. We analyze the impact of the Chairman Statement, Financial Review and Risk Section linguistic features separately, for the UK firms from 2012 to 2017. We estimate the cost of equity through the Price to Earnings Growth Model and the linguistic features are divided between readability and sentiment (tone). We find that disclosure content has an impact on cost of equity, while readability has is associated with no impact on cost of equity. We also find that positive tone is associated with lower cost of equity in all sections of the Annual Report.

  • Contributo dos modelos de economia de partilha na sustentabilidade : paradigma português
    Publication . Gonçalves, João Pedro Fernandes; Julião, Jorge Manuel Soares; Gaspar, Marcelo
    A economia de partilha é um modelo que tem por base a interação entre indivíduos, facilitando substancialmente o momento de aquisição do bem ou do serviço, uma vez que é potenciado por plataformas digitais. Face a estas características e aliada ao facto de potenciar a redução de custos (Richardson,2015), há uma relação com a sustentabilidade. Porém, a bibliografia não demonstra que este ideário, de conciliar a economia de partilha com a sustentabilidade, esteja atingido. A presente investigação teve como objetivo explorar a relação entre modelos de economia de partilha e a sustentabilidade em Portugal, para além de perspetivar esclarecer os setores onde esta propensão é maior. Do ponto de vista metodológico foi organizada como estudo de casos múltiplos, incidindo em quatro empresas de três setores diferentes, analisou a perspetiva organizacional e institucional dos modelos de partilha, visões e interações com a sustentabilidade. Em Portugal, o setor do alojamento P2P (Airbnb) e transporte P2P (Free Now) são os mais representativos (em termos de receitas geradas), no entanto, o setor de serviços profissionais ao domicílio que engloba as entregas de refeições ou compras (Glovo) e a realização de serviços, como carpintaria, jardinagem, entre outros (Fixando), tem vindo a ganhar bastante protagonismo. Através desta investigação observou-se que, todas as empresas de economia de partilha analisadas têm preocupações para lá do benefício económico. Desta forma, o pilar social da sustentabilidade é transversal a toda a unidade de análise, enquanto o pilar ambiental só está atingido em dois dos três setores estudados.

  • Evaluation of willingness for sharing personal mobile data according to benefits
    Publication . Castro, Maria Catarina da Silva Pereira; Julião, Jorge Manuel Soares; Serrano, Luís Manuel Ventura
    Currently, we live in a pandemic context, caused by the SARS-CoV-2 virus. If technology was already part of the daily life of a large part of the population, in this context, it came to be accentuated and to identify itself as a possible tool to help control and combat this virus. Mobile applications have been positioning themselves more sharply in the market and a range of them require the user to share their personal geolocation data. This type of personal data is associated with benefits and risks, and the motivation to share them in different areas of activity is an innovative investigation. Being the objective of this research to evaluate the acceptance of sharing of personal geolocation data, according to benefits perceived by mobile application users; a qualitative study using multi-methods was designed to obtain more consistent results. Initially, an exploratory study was conducted, and an online questionnaire was subsequently launched. The sample made it possible to analyse the responses of residents in Portugal. Through the results of the research, we can conclude that the motivation to share personal geolocation data changed depending on the proposed area, and the health area was the one that was evaluated with greater willingness to share, followed by the transport area and leisure area. Additionally, when a specific benefit is proposed to the user, in all areas there is an increase in the willingness to share their personal geolocation data. The current context of Covid-19 impacted the willingness to share, given that a significant part of the sample claims to have more desire to share geolocation data in the current context than before it.

  • Consumer perceived value of sustainably produced wine
    Publication . Dias, Irene Beatriz Tiago da Silva; Julião, Jorge Manuel Soares; Gaspar, Marcelo
    The world has becoming increasingly competitive, with companies adopting their best and boldest strategies in order to keep up with innovation and globalization. The wine industry is one example of such changes. Consumer behavior is adjusting to new trends, such as health and environmental concerns that affect consumer’s purchases. Sustainability is now a distinguishing element within differentiation strategies that companies are implementing. Thus, the relevance of sustainable products and, therefore, the adoption of sustainable practices within the wine production, is a valuable insight for wine producers to improve and adjust their communication strategies regarding this matter. This research aims at characterising the value that sustainably produced wine has for consumers, including their predisposition for an additional payment regarding sustainable wine. For this purpose, a quantitative researchc was conducted, using an online questionnaire where the data was treated in a statistical program. With a sample of 257 surveyees, the results obtained showed that most of the respondents value and are willing to pay more for a wine that was produced with sustainable practices. This willingness to pay was greater for women and younger age groups.

  • A pessoa humana : reflexão didáticopedagógica sobre a unidade letiva 1 do 6.º ano
    Publication . Cruz, João Luís Pedrosa da; Castro, José Acácio Aguiar de
    O presente relatório é o culminar da unidade curricular da prática de ensino supervisionado, integrado no Mestrado em Ciências Religiosas especialização em Educação Moral e Religiosa Católica, da Universidade Católica Portuguesa, centro regional do Porto. Nas páginas que se seguem apresento um pouco do conhecimento que absorvi na frequência das unidades curriculares lecionadas no Mestrado. De todas as unidades curriculares retirei algo que me foi útil na elaboração deste relatório e que servirá na prática profissional. O foco deste relatório está no estágio curricular e em particular na UL 1, do sexto ano do ensino básico: “A Pessoa Humana”. “Quem é a Pessoa?” É a questão inicial da unidade letiva em estudo. É neste sentido que a reflexão teológica que apresento, se desenvolve. Procurando em primeiro lugar delinear a importância que o termo Pessoa tem para a teologia percorrendo um pouco da história do conceito, conduzindo-nos para conclusão de que a Pessoa é um ser de relação, mas também um ser que é sujeito e objeto de si própria.
